Optical disk replay device

An optical disk replay device, comprising:

• an optical pickup which irradiates laser light upon a track of an optical disk and receives light reflected therefrom;
• a tracking actuator for shifting an objective lens of the optical pickup in a tracking direction;
• a tracking error signal detection circuit which outputs a tracking error signal based upon the reflected light received by the optical pickup;
• a phase compensation circuit which generates a tracking drive signal based upon the tracking error signal, and outputs this tracking drive signal to the tracking actuator;
• a balance compensation value calculation circuit which calculates a balance compensation value for the tracking error signal according to the tracking drive signal outputted by the phase compensation circuit;
• and
• a balance compensation circuit which adds this balance compensation value to the tracking error signal detected by the tracking error signal detection circuit, and inputs this compensated value to the phase compensation circuit.
